subtree-splitter action

This actions synchronizes a monolithic repository to standalone repositories by using splitsh-lite.

Usage

Inputs

Specify using with keyword

  • config-path - (Required) Location of the subtree split mapping configuration
  • batch-size - How many subtreesplits should be processed in parallel. It is recommended to keep this amount low (or even at 1) for large repositories.

Example workflow

Configuration

Create a configuration file with the mapping of the different subtree splits. Each subtree split item contains a name (must be unique), directory in the current repository and a target git repository.

{
    "subtree-splits": [
        {
            "name": "core",
            "directory": "src/Core",
            "target": "[email protected]:example/core-package.git"
        }
    ]
}

Workflow

Example workflow to sync commits and tags.

on:
    push:
        # Only trigger for specific branches or changes in specific paths.
        branches:
            - '*'
        paths:
            - src/**
        # Tag push events should be ignored, they will be handled with the create event below.
        tags-ignore:
            - '*'
    create:
        tags:
            - '*'
    delete:
        tags:
            - '*'
